Replace Rear Brake Shoes Drums and Adjust
Removing the Wheel Cylinder After the rear brake shoe and hardware pieces have been removed, install line wrench onto brake line at the wheel cylinder and loosen the mounting fitting, then remove it. Note: brake fluid will leak from line when loosened. Remove wheel cylinder mounting bolts and replace wheel cylinder with new unit. Re-attach and tighten brake lines and retighten wheel cylinder mounting bolts. Then clean and lube the brake shoe backing plate. Step 5 - Reassemble With New Brake Parts
Reassemble with New Brake Part Components Reassemble with new brake parts and make sure all the brake hardware is mounted correctly. Note: when changing rear brake shoes, only disassemble one side at a time so you always have a reference copy on the side that is still together. Step 6 - Adjusting Brake Shoes
Adjusting Rear Brake Shoes After brake shoes have been installed they need to be adjusted. Normally they are self adjusting but the first time after installation, a primary adjustment must be made. After installing the brake drum and spinning it on the bearing hub, adjust the brake shoes to lightly contact the brake drum and recheck regularly. After the brake shoes are adjusted, bleed the brake system until free from air in the brake fluid and leaks. Test brake system before driving. CAUTION: DO NOT DRIVE OR MOVE VEHICLE UNTIL NORMAL BRAKE PEDAL OPERATION IS PRESENT! Common Problems
- Brake shoes wear out and grind to metal due to lack of maintenance.
- Low brake pedal due to improper adjustment.
- Looses partial braking ability when wet.
Rear Brake Shoes and Drums
|Rear Brake Shoes - The rear brake shoe is actuated by wheel cylinders that force the brake shoe against the brake drum with hydraulic pressure from the master cylinder.|
||Wheel Cylinder - Brake fluid pressure from the brake master cylinder is applied to the brake wheel cylinder forcing the brake shoe against the brake drum.|
||Brake Drum - The brake drum is used to slow the wheel speed through braking action. The brake shoes are applied to the drum to cause friction.|
